AJ and JLS star Oritsé welcomed their son on Sunday 24 August. This is the couple's first child together.
Stepping Out star AJ announced the news on Twitter last night (26 August). She said: "So happy to announce that on Sunday 24th at 1.49am we welcomed our precious baby boy, weighing 6lbs 3oz to the Azari-Williams family."
She added: "So in love with our precious baby boy!!!! @Oritse."
An overwhelmed Oritsé also took to Twitter to announce the happy news. He wrote: "I watched in awe as @AJAzari gave birth to our 1st born son on Sunday 24th at 1.49am. He is my Treasure of life! x."
The couple are yet to reveal the name of their newborn.

The couple received tons of congratulatory messages from fans, showbiz pals and Oritsé's former JLS bandmates.

Meanwhile, JB Gill, who is expecting his first child with wife Chloe, said: "Such amazing news!!! Congratulations! Over the moon for @Oritse and @AJAzari what a beautiful gift from God. Can't wait to meet him!"
In July, Oritsé and AJ announced that they were expecting their first child together, revealing the news with a very cute photo of a heavily pregnant AJ showing off her baby bump.
Oritsé is now the second member of JLS to become a father. Marvin welcomed his first child - daughter Alaia-Mai - with wife Rochelle in May last year.
Congratulations, Oritsé and AJ!
